Given a set of keywords, we find a maximum Web query (containing the most keywords possible) that respects user-defined bounds on the number of returned hits. We assume a real-world setting where the user is not given direct access to a Web search engine's index, i.e., querying is possible only through an interface
Search engine marketing provided by search engines enable companies to promote their products to internet users based on their queries is now a major online advertising channel.

enterprises adopt the method based on search engine optimization (SEO) to implement search engine marketing (SEM). Besides, in order to help enterprises to monitor the SEO performance of website, and constantly enhance overall competitiveness of website on the Internet, we proposed a SEO monitoring strategy based on keywords
based on keyword indexing, there are many records in their result lists that are irrelevant to the user's information needs. It is shown that for retrieving more relevant and precise results, the following two points should be concerned: First of all, the query (either it is generated by a human or an intelligent agent
The Web has the potential to become the world's largest knowledge base. In order to unleash this potential, the wealth of information available on the Web needs to be extracted and organized. There is a need for new querying techniques that are simple and yet more expressive than those provided by standard keyword
information appears. To the best of our knowledge, this is the first solution seen in such a service in the mobile Internet era. First, our tracking engine called Tianji crawls the web pages based on time priority and constructs a new index structure, which enables a faster match of web pages to related keywords. Then, we
plus noun phrase learning for extraction of activity concepts in Chinese. We also propose an algorithm of relevance measurement for extracting relation instances by binary keywords based on co-occurrence statistics. Finally, we build a practical system of ontology learning through learning relation instances of the
This paper described our development dialog system on Kyoto tourist information assistance. Dialog part of our system helped user to make an appropriate query. Information analysis part would be assisted for user to select the retrieved information. Nowadays we can get most information through the Internet.

We define the concept of a search skeleton for topic conversion. A search skeleton represents relationships between keywords in a query. A given
