چکیده
In TREC 2016, we focus on tackling the challenges posed by the Dynamic Domain (DD) track. The goal of the TREC DD track is to support research in dynamic, exploratory search within a complex domain. To this end, our participation investigates the suitability of multiple diversification approaches for dynamic information retrieval. In particular, based on fine-grained real-time feedback obtained from a simulated user, we apply diversification strategies that make use of single-source as well multi-source information for mining flat or hierarchical query aspects.

TREC 2016 Dynamic Domain Track Overview
The main goal of TREC dynamic domain track is to explore and evaluate systems for interactive information retrieval, which reflects real-world search scenarios. Due to the importance of learning from user interactions, this track has been held for the second year. The name of the track contains two parts. “Dynamic” means that the search system dynamically adapts the provided ranking to the user...

Search tasks for professional searchers, such as law enforcement agen-cies, police officers, and patent examiners, are often more complex thanopen domain Web search tasks. When professional searchers look for rele-vant information, it is often the case that they need to go through multipleiterations of searches to interact with a system. The Dynamic DomainTrack supports rese...
متن کاملLaval University at TREC Dynamic Domain 2016: Subtopic extraction focused on Named Entities
— This paper describes the results submitted by Laval University to the TREC 2016 Dynamic Domain track. We submitted five runs. For this year we decided to focus around Named Entities to interpret the subtopics. Named Entities are one of the two types of queries we identified in this challenge, the other being queries about concepts. We describe in this paper our experiments to determine if tar...

The TREC Dynamic Domain search task addresses search scenarios where users engage interactively with search systems to tackle domain specific information needs. In our participation, we focused on utilizing passage-based representations in document retrieval and user feedback processing. In addition, we submitted a baseline retrieval method and a manual run that considers only relevant document...
متن کاملDynamic Response of the Coupled Vehicle-Floating Slab Track System using Finite Element Method
In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...
