On Querying and Exploring Activities on a User's Desktop

S. Adali, S. Pearce, M. Sapino
2006 22nd International Conference on Data Engineering Workshops (ICDEW'06)  
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.  ...

2016 Procedia Computer Science  
Data on one's personal computer (PC) is continue to increase day by day and it has made need of managing personal desktop data as an active area of research.  ...  Managing desktop data includes an efficient way of searching and retrieving desired data and information from it.  ...  Modelling and querying of heterogeneous desktop data further increases the complexity for developing a desktop search system.  ...

Identifying User Sessions in Interactions with Intelligent Digital Assistants

2017 Proceedings of the 26th International Conference on World Wide Web Companion - WWW '17 Companion  
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  ...

Task detection for activity-based desktop search

Sergey Chernov
2008 Proceedings of the 31st annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '08  
We propose to exploit collected information about user activities with desktop files and applications for activity-based desktop search.  ...  The desktop search tools provide powerful query capabilities and result presentation techniques. However, they do not take the user context into account.  ...  RESEARCH QUESTIONS 1.1 Data Acquisition. A first problem for activitybased desktop search design is data acquisition using implicit feedback.  ...

Context-aware Search for Personal Information Management Systems [chapter]

2012 Proceedings of the 2012 SIAM International Conference on Data Mining  
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.  ...

Personalization as a service

Hang Guo, Jidong Chen, Wentao Wu, Wei Wang
2009 Proceeding of the first international workshop on Cloud data management - CloudDB '09  
The client side program records user activities on personal devices such as PC. Besides that, the user model is also computed on the client side to avoid server overhead.  ...  The cloud side program fetches the user model periodically and adjusts its results accordingly. We build a personalized cloud data search engine prototype to prove our idea.  ...  The model synchronizer serves cloud side services by executing their queries for user models. We implemented a cloud data search prototype as our case study.  ...
