Research on Automatic Classification for Deep Web Query Interfaces

2008 International Symposiums on Information Processing, 2008
In recent years, the Web is "deepened" rapidly and users have to browse quantities of Web sites to access Web databases in a specific domain. So, to build an unified query interface which integrates query interfaces of a domain to access various Web databases at the same time becomes a very important issue.

Query Topic Classification and Sociology of Web Query Logs

Computación y Sistemas, 2015
In the paper, the objects, tasks, and a general procedure of the sociological analysis of Web search engine query logs are described and illustrated by a methodologically complete study of the cross-nation search image changes based on two-year spaced query logs of the national search audience.

Automatic web query classification using labeled and unlabeled training data

Proceedings of the 28th annual international ACM SIGIR conference on Research and development in information retrieval, 2005
Accurate topical categorization of user queries allows for increased effectiveness, efficiency, and revenue potential in general-purpose web search systems. Such categorization becomes critical if the system is to return results not just from a general web collection but from topic-specific databases as well.

Semantics-Assisted Deep Web Query Interface Classification

Proceedings of the Eighth International C* Conference on Computer Science & Software Engineering - C3S2E '15, 2008
Huge amounts of structured data sources are hidden in the databases behind web forms. Volumes of deep web contents were estimated to be around 500 times those of surface web. However, many web forms are not deep web query interfaces. To retrieve contents in the web databases, an important task is to identify those web forms that are deep web query ...

Identification and Classification of Deep Web Query Interfaces via Ontology

International Journal of Advancements in Computing Technology, 2011
In order to obtain the large quantities of valuable information on Deep Web, it is required to discover the related individual query interface and design the integrated query interface on which user query request can be submitted. The key challenges are to identify and classify the Deep Web query interface accurately.

Research on Web Page Classification Method Based on Query Log

Journal of Shanghai Jiaotong University (Science), 2018
Web page classification is an important application in many fields of Internet information retrieval, such as providing directory classification and vertical search. Methods based on query log which is a light weight version of Web page classification can avoid Web content crawling, making it relatively high in efficiency, but the sparsity of user ...

Automatic classification of deep web databases with simple query interface

2009 International Conference on Industrial Mechatronics and Automation, 2009
Deep Web database classify is a key operation in organizing Deep Web resources. We address the problem of identifying the domain of web databases with simple query interface. The existing methods can not effectively classify this type of web databases, to solve this problem, we propose an new framework that can automatically and accurately classify web

Deep Web Data Source Classification Based on Query Interface Context

2012 Fourth International Conference on Computational and Information Sciences, 2012
As the volume of information in the Deep Web grows, a Deep Web data source classification algorithm based on query interface context is presented. Two methods are combined to get the search interface similarity. One is based on the vector space. The classical TF-IDF statistics are used to gain the similarity between search interfaces.

A Feature-Free Flexible Approach to Topical Classification of Web Queries

2011 Seventh International Conference on Semantics, Knowledge and Grids, 2011
The task of topical classification of Web queries is to classify Web queries into a set of target categories. Machine learning based conventional approaches usually rely on external sources of information to obtain additional features for Web queries and training data for target categories.

Inducing and Refining Topics for Web Query Classification Using a Semantic Network

Journal of Computational and Theoretical Nanoscience, 2018
Web query classification, the task of inferring topical categories from a web search query is a non-trivial problem in Information Retrieval domain. The topic categories inferred by a Web query classification system may provide a rich set of features for improving query expansion and web advertising.
