PFSgeo: Preference-Enriched Faceted Search for Geographical Data
نویسندگان
چکیده
In this paper we show how an exploratory search process, specifically the Preference-enriched Faceted Search (PFS) process, can be enriched for exploring datasets that also contain geographic information. In the introduced extension, that we call PFSgeo, the objects can have geographical coordinates, the interaction model is extended, and the web-interface is enriched with a map which the user can use for inspecting and restricting his focus, as well as for expressing preferences. Preference inheritance is supported as well as an automatic scope-based resolution of conflicts. We detail the implementation of the interaction model, elaborate on performance and report the positive results of a task-based evaluation with users. The value of PFSgeo is that it provides a generic and interactive method for aiding users to select the desired option(s) among a set of options that are described by several attributes including geographical ones, and it is the first model that supports map-

Hippalus: Preference-enriched Faceted Exploration
In this work we describe and evaluate Hippalus, a system that o↵ers exploratory search enriched with preferences. Hippalus supports the very popular interaction model of Faceted and Dynamic Taxonomies (FDT), enriched with user actions which allow the users to express their preferences. The underlying preference framework allows expressing preferences over attributes (facets), whose values can b...
متن کاملSpecies Identification Through Preference-Enriched Faceted Search
There are various ways and corresponding tools that the marine biologist community uses for identifying one species. Species identification is essentially a decision making process comprising steps in which the user makes a selection of characters, figures or photographs, or provides an input that restricts other choices, and so on, until reaching one species. In many cases such decisions shoul...
متن کاملUsing preference-enriched faceted search for species identification
Species identification is essentially a decision-making process comprising steps in which the user makes a selection of characters, figures or photographs, or provides an input, that restricts other choices, until reaching one species. In some identification methods such decisions should have a specific order. Consequently, a wrong decision at the beginning of the process, could exclude a big s...
متن کاملA Faceted Ontology for a Semantic Geo-Catalogue
Geo-spatial applications need to provide powerful search capabilities to support users in their daily activities. However, discovery services are often limited by only syntactically matching user terminology to metadata describing geographical resources. We report our work on the implementation of a geographical catalogue, and corresponding semantic extension, for the spatial data infrastructur...
متن کاملUNIVERSITÄT AUGSBURG Context-Aware Preference Search for Outdoor Activity Platforms
Complex application domains like outdoor activity platforms demand a powerful search interface that can adapt to personal user preferences and to changing contexts like weather conditions. Today most platforms offer a search technology known as Faceted Search, also named Parametric Search, where a user iteratively adapts his/her search parameters by a tedious and time-consuming trial-and-error ...
