On Querying and Exploring Activities on a User's Desktop

22nd International Conference on Data Engineering Workshops (ICDEW'06)
Preserved Fulltext
Our activity model is well suited to support a query language that is able to alter the context and the definition of an activity to easily visualize complex relationships in data. ...
Many desktop query and management systems offer an object oriented view of a computer, where the emphasis is on describing the information relevant to an object. ...
We would like to thank Ramesh Jain for stimulating discussions on multimedia querying and experiential computing. We also would like to thank Bouchra Bouqata for helpful discussions. ...

It employs an Hidden Markov Model (HMM)based user model, which is learned from user's activity logs, to estimate the query context when he submits the query. ...
Different from other desktop search engines, iMecho ranks results not only by the content of the query, but also the context of the query. ...
Following this observation, we develop a context-aware desktop search system called iMecho. The idea is to build a user behavior model based on the user's previous activities. ...

Instead, we model user-activity times as a Gaussian mixture model and look for evidence of a valley to identify optimal inter-activity thresholds for identifying sessions. ...
To our knowledge, this is one of the first studies investigating user interactions with a desktop based digital assistant. ...
We base our experiments on real world log data and observe that the mixture model fits well to the Cortana desktop interaction data and that empirical data suggests a smaller time threshold (∼2 minutes ...

We developed iMecho (My Memory Echo), an associative memory based desktop search system, which exploits such associations and contexts to enhance traditional desktop search. ...
Traditional desktop search engines only support keyword based search that needs exact keyword matching to find resources. ...
For the same task link, iMecho uses a clustering based algorithm for initial task analysis and an Hidden Markov Model (HMM) method for further optimization. • Besides the traditional keywords-based searching ...

The model is learned from user's past access history and is used to predict user's current activity upon the submission of some keyword query. ...
We observed that in desktop search, the semantics of keyword queries are often context-aware, i.e., they are related to the current activity state (e.g., writing a paper, navigating a website, etc.) of ...
For instance, in [21] , clickthrough data is analyzed to learn user's preference over different semantics of the query. ...
