Abstract: Dynamic Faceted Search Systems have gained prominence in research as one of the exploratory search approaches that support complex search tasks. They provide facets to users about the information space and allow them to refine their

search query and navigate back and forth between resources on a single results page. When the information available in the collection being searched across increases, so does the number of associated facets. This can make it impractical to display all of the facets at once. To tackle this problem, Dynamic Faceted Search employs

for facet ranking. Ranking methods can be based on the information structure, the textual queries issued by the user, or the usage logs. Such methods reflect neither the importance of the facets no

Moreover, the idea of personalizing exploratory search can be challenging and tricky, since personalization in IR (specifically precision-oriented search engines) implicitly implies narrowing and focusing the information space to retrieve the most relevant results according to the users' interests and desires. On the contrary, exploratory search systems are typically recall-oriented and they favor covering as much from the information space as possible. They also encourage diversifying the user knowledge to help them learn and discover the unknown. The generation of a ranked list of facets should be a dynamic

process for a number of reasons. First of all, manually setting up facets is a time consuming task which relies upon domain experts. Second, it is not practical on large, multi-domain datasets. Even one automatic facet generation and ranking might not be suitable for data that changes and grows over time. Lastly, the relevance of facets can be user, query and context dependant. I am proposing a personalized approach to the dynamic ranking of facets. The approach combines different sources of information to recommend the most relevant facets.

Existing Approach

Previous work for the facet mining of this system is to propose the automatically mining facets for queries. The main problem is to find query facets which are multiple groups of words that explain and summarize the information covered by a query in these facets. Existing system introduced a systematic solution, which was referred as QD Miner, to automatically mine query facets by aggregating frequent lists from free text, HTML tags, and repeat regions within top search results. The best option to find the query facets is QD Miner can be improved in many aspects. Ex., some semi supervised bootstrapping list extraction algorithms can be used to extract more lists from the top K results. Specific website wrappers can also be used to extract high lists from authoritative websites. Adding these lists may improve accuracy of query facets. Grammatical feature information can be used to further check the homogeneity of lists and improve the quality of query facets. We will explore these topics to refine facets in the future.
