There are three modes that can be selected: active mode (coaching), passive mode (coached), bidirectional mode (both coaching and coached);

the first mode of operation of the Xiaoming: active mode, as shown in fig. 2:

questions to the user are asked at little initiative:

what is a suspect? Motivation is?

What is the relationship between suspects a and B? The role in this case is?

The historical knowledge base of the knowledge graph comprises: historical knowledge, historical cases, historical conclusions and historical relationships.

The small and clear knowledge graph capability comprises event association, event inference, character association, character recommendation, character analysis, potential problems, possible directions, habit inference, probability analysis and the like.

First, knowledge graph definition, essentially, is a semantic network that reveals relationships between entities. For quickly describing concepts and their interrelationships in the physical world.

The knowledge graph is converted into a simple and clear triple of entities, relations and entities by effectively processing, processing and integrating the data of the complicated document, and finally a great deal of knowledge is aggregated, so that the quick response and reasoning of the knowledge are realized.

The knowledge graph has two construction modes of top-down and bottom-up. The top-down construction is to extract ontology and mode information from high-quality data by means of structured data sources such as encyclopedic websites and the like, and add the ontology and mode information into a knowledge base; the bottom-up construction is that a resource mode is extracted from publicly acquired data by a certain technical means, a new mode with higher confidence coefficient is selected, and the new mode is added into a knowledge base after manual review.

FIG. 9 is a diagram of a knowledge graph, as shown in FIG. 9, if there is a Relationship between two nodes, they are connected by an undirected edge, and then this node is called an Entity (Entity), and this edge between them is called a Relationship (Relationship).

The basic unit of the knowledge graph is a triple formed by an Entity (Entity) -Relationship (Relationship) -Entity (Entity), and the triple is also the core of the knowledge graph.

Entity refers to something that is distinguishable and exists independently. The entity is the most basic element in the knowledge graph, and different relationships exist among different entities. Such as "china", "beijing", "16410 square kilometers", etc. in the figure.

Relationship is a connection between different entities, referring to a connection between entities. And connecting the nodes in the knowledge graph through the relation nodes to form a large graph. Such as "population", "capital", "area", etc. in the figure

Data type and storage mode

The raw data types of a knowledge graph generally have three classes (also three classes of raw data on the internet):

structured Data (structured Data): such as a relational database

Semi-structured Data (Semi-structured Data): such as XML, JSON, encyclopedia

Unstructured Data (unstructured Data): such as pictures, audio, video, text

Logic and technology architecture

1. Logic architecture

The knowledge graph can be logically divided into two levels, namely a mode layer and a data layer.

The mode layer is built on the data layer and is the core of the knowledge graph, and an ontology base is generally adopted to manage the mode layer of the knowledge graph. The ontology is a concept template of the structured knowledge base, and the knowledge base formed by the ontology base has a strong hierarchical structure and a small redundancy degree.

Mode layer: entity-relationship-entity, entity-attribute-property values

The data layer is mainly composed of a series of facts, and knowledge is stored in the unit of facts. If facts are expressed in triplets of (entity 1, relationship, entity 2), (entity, attribute value), graph databases may be selected as storage media, such as open-source Neo4j, Twitter's FlockDB, sones' GraphDB, and so on.

And (3) a data layer: Belgium-wife-Meilin-Gaiz, Belgium-President-Microsoft

2. Technical architecture

Fig. 10 is a schematic diagram of a technical architecture of a knowledge graph, and the overall architecture of the knowledge graph is as shown in fig. 10, wherein a part inside a dashed box is a construction process of the knowledge graph and is also a process of updating the knowledge graph.

The construction and application of the large-scale knowledge base need the support of various intelligent information processing technologies. Knowledge elements such as entities, relationships, attributes and the like can be extracted from some published semi-structured and unstructured data through knowledge extraction technology. Through knowledge fusion, ambiguity between the referent items such as entities, relations and attributes and the fact objects can be eliminated, and a high-quality knowledge base is formed. Knowledge reasoning is to further mine implicit knowledge on the basis of the existing knowledge base, so that the knowledge base is enriched and expanded. The comprehensive vector formed by the distributed knowledge representation has important significance for the construction, reasoning, fusion and application of the knowledge base.

And (3) knowledge extraction: the method is mainly oriented to open link data, and can extract available knowledge units through an automatic technology, wherein the knowledge units mainly comprise 3 knowledge elements of entities (concept extension), relations and attributes, and a series of high-quality fact expressions are formed on the basis of the knowledge units, so that a foundation is laid for constructing an upper mode layer. Knowledge extraction has three main tasks:

and (3) entity extraction: in the art we refer more to the NER (named entity recognition), which refers to the automatic recognition of named entities from the original corpus. Since the entity is the most basic element in the knowledge-graph, the completeness, accuracy, recall rate and the like of the extraction directly influence the quality of the knowledge base. Therefore, entity extraction is the most basic and critical step in knowledge extraction;

and (3) extracting the relation: the aim is to solve the problem of semantic linkage between entities, and early relation extraction mainly identifies entity relations by a method of manually constructing semantic rules and templates. Subsequently, the relationship model between the entities gradually replaces the manually predefined grammar and rules.

And (3) extracting attributes: the attribute extraction is mainly for the entity, and a complete sketch of the entity can be formed through the attribute. Since the attribute of the entity can be regarded as a name relationship between the entity and the attribute value, the extraction problem of the entity attribute can be converted into a relationship extraction problem.

Knowledge representation

In recent years, an expression learning technology represented by deep learning is advanced significantly, semantic information of an entity can be expressed as a dense low-dimensional real-valued vector, and further, the entity, a relationship and complex semantic association between the entities and the relationship are calculated efficiently in a low-dimensional space, so that the method has important significance for construction, reasoning, fusion and application of a knowledge base. The graph embedding is a representation of learning, as friends who pay attention to our public numbers must read the last blog.

Knowledge fusion

Knowledge in the knowledge map has a wide range of knowledge sources, and has problems of good knowledge quality, overlapping knowledge from different data sources, and unclear relation between knowledge, so that it is necessary to perform knowledge fusion. Knowledge fusion is a high-level knowledge organization, so that knowledge from different knowledge sources is subjected to steps of heterogeneous data integration, disambiguation, processing, reasoning verification, updating and the like under the same frame specification, fusion of data, information, methods, experiences and human ideas is achieved, and a high-quality knowledge base is formed.

Among them, knowledge updating is an important part. The cognitive abilities, knowledge reserves and business needs of humans are increasing over time. Therefore, the content of the knowledge graph needs to be advanced, and the knowledge graph, whether a general knowledge graph or an industry knowledge graph, needs to be continuously updated in an iterative mode, existing knowledge is expanded, and new knowledge is added.

Application of knowledge graph

The knowledge graph provides a more effective mode for the expression, organization, management and utilization of massive, heterogeneous and dynamic big data on the Internet, so that the intelligent level of the network is higher and is closer to the cognitive thinking of human beings.

1. Intelligent search

After a user's query is entered, the search engine does not merely look for keywords, but rather first performs semantic understanding. For example, after the query is participled, the description of the query is normalized so that it can be matched with the knowledge base. The returned result of the query is a complete knowledge system given by the search engine after searching the corresponding entity in the knowledge base.

2. Deep question and answer

The question-answering system is a high-level form of an information retrieval system and can provide users with answers to questions in accurate and concise natural language. Most of the question-answering systems tend to decompose a given question into a plurality of small questions, then extract matched answers one by one from a knowledge base, automatically detect the matching degree of the answers in time and space and the like, and finally combine the answers and display the answers to users in a visual mode.

The intelligent voice assistant Siri of the apple can provide services such as answers, introduction and the like for the user, and is a result of introducing the knowledge graph. Knowledge maps allow machine-to-human interaction to appear more intelligent.

Fourthly, construction of knowledge graph

The first step is as follows: information extraction

Information extraction (information extraction) is the 1 st step of knowledge graph construction, and the key problems are as follows: how to automatically extract information from heterogeneous data sources to obtain candidate indication units.

Information extraction is a technique for automatically extracting structured information such as entities, relationships, and entity attributes from semi-structured and unstructured data.

The related key technologies comprise: entity extraction, relationship extraction and attribute extraction.

The second step is that: knowledge fusion

Knowledge fusion includes 2 parts of content: entity linking, knowledge consolidation

1. Entity linking (entity linking): the method refers to an operation of linking an entity object extracted from a text to a corresponding correct entity object in a knowledge base.

The basic idea is to first select a set of candidate entity objects from the knowledge base according to a given entity designation, and then link the designation to the correct entity object through similarity calculation.

Study history:

only how to link the entities extracted from the text into the knowledge base is concerned, ignoring the semantic connections that exist between entities located in the same document.

Attention is being turned to exploiting co-occurrence relationships of entities while linking multiple entities into a knowledge base. Namely, integration entity linking (collecting entity linking)

Entity linking process:

and extracting entity name items from the text through the entities.

And carrying out entity disambiguation and coreference resolution, and judging whether the same-name entities in the knowledge base represent different meanings and whether other named entities exist in the knowledge base and represent the same meanings.

After confirming the corresponding correct entity object in the knowledge base, linking the entity designation chain to the corresponding entity in the knowledge base.

Entity disambiguation: the technology specially used for solving the problem of ambiguity generated by the same-name entity can accurately establish entity link according to the current context through entity disambiguation, and the entity disambiguation mainly adopts a clustering method. It can also be thought of as a context-based classification problem, similar to part-of-speech disambiguation and sense disambiguation.

Performing coreference resolution: the method is mainly used for solving the problem that a plurality of designations correspond to the same entity object. In a session, multiple references may point to the same entity object. These terms can be associated (merged) to the correct entity object using coreference resolution techniques, which attracts a lot of research efforts due to the special importance of this problem in the fields of information retrieval and natural language processing. Coreference resolution also has some other names such as object alignment, entity matching, and entity synonymity.

2. And (3) knowledge merging: in constructing the knowledge graph, knowledge input may be obtained from third party knowledge base products or existing structured data.

Common knowledge consolidation requirements are two, one is to consolidate external knowledge bases and the other is to consolidate relational databases.

Fusing the external knowledge base to the local knowledge base requires handling two levels of problems:

the fusion of data layers, including the designation, attribute, relationship and belonging category of the entity, has the main problem of how to avoid the conflict between instances and relationships, resulting in unnecessary redundancy

Fusing newly obtained ontology into the existing ontology library through the fusion of the mode layer

Then, the relational database is merged, and an important high-quality knowledge source is the own relational database of an enterprise or an organization in the process of constructing the knowledge graph. In order to incorporate these structured historical data into the knowledge graph, a Resource Description Framework (RDF) may be employed as a data model. This data conversion process is referred to figuratively by the industry and academia as RDB2RDF, which is essentially the conversion of data from a relational database into triple data of RDF.

The third step: knowledge processing

In the foregoing, we have extracted knowledge elements such as entities, relationships, attributes, and the like from the original corpus through information extraction, and have removed ambiguity between entity names and entity objects through knowledge fusion, to obtain a series of basic fact expressions.

However, the fact itself is not equal to knowledge. To finally obtain a structured and networked knowledge system, a knowledge processing process is required.

The knowledge processing mainly comprises 3 aspects: ontology construction, knowledge reasoning and quality assessment.

1. Ontology construction

Ontology refers to a concept set, concept framework, such as "people", "things", etc., of a worker.

The ontology can be manually constructed in a manual editing mode (by means of ontology editing software) or can be constructed in a data-driven automatic mode. Because the workload of the manual mode is huge and experts meeting the requirements are difficult to find, the current mainstream global ontology library products are obtained by gradually expanding the existing ontology libraries oriented to specific fields by adopting an automatic construction technology.

The automated ontology building process comprises three phases:

similarity calculation of entity parallel relation

Entity context extraction

Generation of ontologies

Fig. 11 is a schematic diagram of the construction of the body, as shown in fig. 11: when the knowledge graph obtains three entities, namely the entities of the Alibab, the Tencent and the mobile phone, the knowledge graph may think that the three entities have no difference, but when the knowledge graph calculates the similarity between the three entities, the knowledge graph finds that the Alibab and the Tencent are likely to be more similar and have larger difference with the mobile phone.

This is the first step, but in this way, the knowledge map does not actually have the concept of upper and lower layers, and it is unknown that the agilawood and the mobile phone are not in the same type at all and cannot be compared. Therefore, we need to complete the above work in the step of extracting the context in the entity, so as to generate the ontology of the third step.

When the three steps are completed, the knowledge graph may understand that "Alibara and Tencent, which are actually the subdivisions of the company as one entity. They are not generic to handsets. "

Knowledge reasoning

After we have completed this step of ontology construction, a prototype of the knowledge-graph has been built. However, most of the relations between knowledge maps are incomplete at this time, and the missing values are very serious, so that at this time, a knowledge reasoning technology can be used to complete further knowledge discovery.

We can find that: if A is the spouse of B, B is the chairman of C, and C is located at D, then we can consider that A lives in the city of D.

According to the rule, we can dig out whether there are other paths in the graph to satisfy the condition, and then we can associate two AD. In addition, we can think that a ring in the series is the chairman of B being C, then CEO of B being C, COO of B being C, is not a ring that can also be used as the inference strategy?

Of course, the object of knowledge inference is not limited to the relationship between entities, and may be the attribute values of the entities, the conceptual hierarchical relationship of the ontology, and the like.

Reasoning attribute values: knowing the birthday attribute of an entity, the age attribute of the entity can be obtained through reasoning;

reasoning concept: it is known that (Tiger, family, Felidae) and (Felidae, order, Carnivora) can be deduced (Tiger, order, Carnivora)

Fig. 12 is a schematic diagram of logic-based reasoning, fig. 13 is a schematic diagram of graph-based reasoning, and fig. 14 is a schematic diagram of deep learning-based reasoning, and as shown in fig. 12-14, the algorithm of the block can be mainly classified into 3 categories, logic-based reasoning, graph-based reasoning and deep learning-based reasoning.

Fifth, summarize

Through the knowledge map, the information of the internet can be expressed into a form closer to the human cognitive world, and a mode for better organizing, managing and utilizing mass information is provided. The current knowledge-graph technology is mainly used for intelligent semantic search, mobile personal assistant (Siri) and deep question and answer system (Watson), and the core technology supporting the applications is the knowledge-graph technology.

In the intelligent semantic search, when a user initiates a query, a search engine can analyze and reason the keywords queried by the user by the aid of a knowledge graph, then map the keywords to one or a group of concepts in the knowledge graph, and then return a graphical knowledge structure to the user according to the concept hierarchy of the knowledge graph, namely a knowledge card seen in Google and hundred-degree search results.

In deep question-and-answer applications, the system also performs semantic analysis and syntax analysis on questions posed by a user using natural language with the help of a knowledge graph, converts the questions into query sentences in a structured form, and queries answers in the knowledge graph. For example, if the user asks: "how to determine if an ebola virus infection is present? If so, then the query may be equivalently transformed into? And then performing reasoning transformation to finally form equivalent triple query sentences, such as (ebola, symptom. If the user's question cannot be answered by reasoning due to the imperfect knowledge base, the deep question-answering system can also feed back the search result to the user by using the search engine, and update the knowledge base according to the search result, thereby preparing in advance for answering subsequent questions.

The key point of the present invention is to use open questions to guide users or robots (Xiaoming) to use knowledge graph technology to perform deep summarization to obtain answers.
