Towards a Unified Framework for Inference with Aggregated Relational Data
Aggregated Relational Data (ARD), originally introduced by Killworth et al. (1998) as “How many X’s do you know” survey questions, are a common tool for observing social networks indirectly. Previous methods for ARD estimate specific network features, such as overdispersion. We suggest a more general approach to understanding social structure using ARD based on a latent space framework. We firs...
متن کاملAggregated Search
To support broad queries or ambiguous information needs, providing diverse search results to users has become increasingly necessary. Aggregated search attempts to achieve diversity by presenting search results from different information sources, so-called verticals (image, video, blog, news, etc), in addition to the standard web results, on one result page.

متن کاملAggregated search: From information nuggets to aggregated documents
The aggregated search assembles in one interface information from different sources. It deals with different types of content (text, video, image, etc) and granularities of retrieval. It aims to assemble the retrieved content forming an aggregated result. This is in contrast with the common approach which provides a list of documents as the search result. Today we are able to retrieve content o...
متن کاملAggregated Subset Mining
The usual data mining setting uses the full amount of data to derive patterns for different purposes. Taking cues from machine learning techniques, we explore ways to divide the data into subsets, mine patterns on them and use post-processing techniques for acquiring the result set. Using the patterns as features for a classification task to evaluate their quality, we compare the different subs...
متن کاملReputation as Aggregated Opinions
A model of reputation is presented in which agents share and aggregate their opinions, and observe the way in which their opinions effect the opinions of others. A method is proposed that supports the deliberative process of combining opinions into a group’s reputation. The reliability of agents as opinion givers are measured in terms of the extent to which their opinions differ from that of th...
