Abstract

The invention discloses a tax knowledge middle platform based on natural language understanding and a construction method of the platform. The tax knowledge middle platform comprises a knowledge alignment module, a knowledge understanding module and a knowledge interaction module. When the middle platform is constructed, the three modules are respectively constructed by comprehensively utilizing natural language processing technologies such as a knowledge graph, search and recommendation. The platform can be used as an entrance for knowledge query in the tax policy field, efficient association, updating, retrieval and learning of multi-source tax knowledge are achieved, the platform is suitable for tax-related workers and can also be used as a platform for tax payment individuals or enterprise related personnel to learn tax policy knowledge, and a question-answering system in the tax policy field can also be constructed based on the platform.

Example Embodiment

[0035]Example 1
[0036]Taking into account the characteristics of multiple tax policy knowledge sources, strong policy, strong professionalism, irregular updates, and strong regionality, this embodiment discloses a tax knowledge platform based on natural language understanding, which can be widely used at all levels Use by tax bureaus, various enterprises, institutions and individuals. Such asfigure 1As shown, this knowledge center includes a knowledge alignment module, a knowledge understanding module, and a knowledge interaction module.
[0037]The knowledge alignment module is used to realize the arrangement and knowledge alignment of multi-source tax policy knowledge, and construct highly structured data; the arrangement refers to the localization of multi-source knowledge, and alignment refers to the deduplication and prioritization of multi-source knowledge .
[0038]The knowledge understanding module uses multi-dimensional natural language understanding technology to realize the association of multi-source tax policy knowledge, the construction of hierarchical knowledge tags and the information extraction of paragraph-level content, so as to realize the chapter-level and paragraph-level understanding of tax policy knowledge.
[0039]The knowledge interaction module realizes the multi-dimensional display of multi-source tax knowledge. Through semantic generalization and semantic association algorithm, users can extract and view the chapter-level and paragraph-level answers of tax policy knowledge through the knowledge interaction module.

Example Embodiment

[0040]Example 2
[0041]This embodiment discloses a method for constructing a tax knowledge center, including the following steps:
[0042]S01). Construct a knowledge alignment module. The knowledge alignment module is used to organize and align the knowledge of multi-source tax policies, and build highly structured data; the arrangement here refers to the localization of multi-source knowledge, and the alignment refers to multi-source knowledge. De-duplication and prioritization of knowledge.
[0043]The specific steps to construct a knowledge alignment module are:
[0044]S11), build a local structured tax policy knowledge base model based on a structured database, and realize the structured arrangement of tax knowledge on this basis;
[0045]In this embodiment, the structured database is a relational database or a Mysql database.
[0046]S12) Organize typical tax policy knowledge sites and build a typical site library;
