Entity Query Feature Expansion Using Knowledge Base Links

Recent advances in automatic entity linking and knowledge base construction have resulted in entity annotations for document and query collections. For example, annotations of entities from large general purpose knowledge bases, such as Freebase and the Google Knowledge Graph. Understanding how to leverage these entity annotations of text to improve ad hoc document retrieval is an open research area. Query expansion is a commonly used technique to improve retrieval effectiveness. Most previous query expansion approaches focus on text, mainly using unigram concepts. In this paper, we propose a new technique, called entity query feature expansion (EQFE) which enriches the query with features from entities and their links to knowledge bases, including structured attributes and text. We experiment using both explicit query entity annotations and latent entities. We evaluate our technique on TREC text collections automatically annotated with knowledge base entity links, including the Google Freebase Annotations (FACC1) data. We find that entity-based feature expansion results in significant improvements in retrieval effectiveness over state-of-the-art text expansion approaches

Just What Community Psychologists Would Do: A Commentary on the Special issues

The papers in these two Global Journal special issues focus on the 18 Community Psychology Practice Competencies proposed by the Society for Community Research and Action (SCRA) in 2012. In this commentary, I articulate some of my enjoyment in reading the articles in these special issues, share some thoughts on the history of the practice competencies, and propose some ideas for conversations that may be useful in their development over time. The SCRA practice competencies have been useful in opening conversations about how to articulate what community psychologists can do in working with community members, and about how to provide educational practices to prepare students for that work. These special issues build on the volume on community psychology practice edited by Scott and Wolfe (2015) and the earlier Global Journal special issue on international competencies (Wolfe, Scott, & Jimenez, 2013). The practice competencies can be useful only if we consider them to be inevitably incomplete descriptions of community psychology practices – practices that are inherently dynamic, contextual, and value-laden. They can be useful only if we continually re-examine and revise them, and adapt them as needed for work in specific contexts

USE OF BODY COMPOSITION IMAGING TO CALCULATE 3-D INERTIAL PARAMETERS FOR INVERSE DYNAMIC ANALYSIS OF YOUTH PITCHING ARM KINETICS

The objectives of this study were to 1) calculate participant-specific segment inertial parameters using dual energy X-ray absorptiometry (DXA) data (referred to as full DXA-driven parameters) and compare the pitching arm kinetic predictions using full DXA-driven inverse dynamics vs scaled, DXA mass-driven (using DXA masses but scaled centers of mass and radii of gyration), and DXA scaled inverse dynamics(ID) (using the full DXA-driven inertial parameters averaged across all participants), 2) examine associations between full DXA-driven kinetics and body mass index (BMI) and 3) examine associations between full DXA-driven kinetics and segment mass index (SMI). Eighteen 10- to 11- year-olds pitched 10 fastballs. DXA scans were conducted and examined to obtain 3D inertial parameters of the upper arm, forearm, and hand. Full DXA-driven and scaled inertial parameters were compared using paired t-tests. Pitching arm kinetic predictions calculated with the four methods (i.e. scaled ID, DXA mass-driven ID, full DXA-driven ID, and DXA scaled ID) were compared using a repeated measures ANOVA with Tukey post-hoc tests. The major results were that 1) full DXA-driven participant specific inertial parameters differed from scaled inertial parameters 2) kinetic predictions significantly varied by method and 3) full DXA-driven ID predictions for shoulder compression force and shoulder internal rotation torque were significantly associated with BMI and/or SMI
