Outline

Research on meta-search engine based on domain ontology

Basic Information

A metasearch engine is a search tool that integrates the results of multiple search engines

Domain ontology is a formal knowledge representation model

Metasearch engine based on domain ontology uses domain ontology to solve information search problems

Advantage

Combines the results of multiple search engines to provide more comprehensive and accurate search results

Use domain ontology to filter and sort search results to improve the relevance and quality of results

Avoid users needing to repeatedly search for the same keywords in multiple search engines

Provide a personalized search experience and flexible search options

Customize the sorting and display of search results based on user preferences and needs

Support users to customize domain ontology to meet search needs in specific fields

Strong scalability, suitable for search scenarios in different fields and sizes

The construction and maintenance of domain ontology can be flexibly adjusted as needed

Metasearch engines can integrate multiple search engines to cover a wider range of information sources

Function

Construction and maintenance of domain ontology

Determine the domain scope and key concepts, and collect and organize relevant domain knowledge

Establish a model for ontology to represent domain knowledge, including concepts, attributes, relationships, etc.

Integration and docking of metasearch engines

Collect and integrate APIs from multiple search engines to achieve acquisition and integration of search results

Define data structures and algorithms to fuse and sort results from different search engines

User interaction and search result display

Provide user interface and interaction methods to support users to submit search requests and browse search results

Adjust the display method and sorting rules of search results based on user search intentions and feedback

Application scenarios

academic research areas

Provide interdisciplinary and comprehensive academic information search services

Support scholars to find literature, experts and research projects in related fields

Technical field

Provides comprehensive search for technical issues and access to solutions

Support developers to find relevant open source code, technical documentation and community discussions

Commercial areas

Provide search and analysis of business information such as market research and competitive intelligence

Enable enterprises to find relevant products, suppliers and business partners

challenge

The construction and maintenance of domain ontology is a heavy workload and requires the participation of professional knowledge workers

Different search engines have different data formats and sorting algorithms, making it difficult to integrate and fuse results.

Users’ search needs and preferences are diverse, and the accuracy and effectiveness of personalized searches are difficult to guarantee.

development trend

The development of automatic construction and update technology of domain ontology to reduce the burden of knowledge workers

Integration and processing of multimodal information to provide richer and more accurate search results

Combine machine learning and natural language processing technology to improve the accuracy and effectiveness of personalized search
