Keyword-Based Querying of Points of Interest Prof. Christian S. Jensen-SFB/TR 8 Colloquium Aalborg University

The web is being accessed increasingly by users for which an accurate geo-location is available, and a spatial, or geographical, web is surfacing where content is associated with locations, resulting in so-called Points of Interest, that are used in a wide range of location-based services. In particular, studies suggest that each week, several billions of web queries are issued that have some form of local intent and that target Points of Interest with locations and textual descriptions.

This state of affairs gives prominence to spatial web data management, and it opens to a research area full of new and exciting opportunities and challenges. A prototypical spatial web query takes a user location and user-supplied keywords as arguments, and it returns Points of Interest that are spatially and textually relevant to these arguments. Due perhaps to the rich semantics of geographical space and its importance to our daily lives, many different kinds of relevant spatial web queries may be envisioned.

Based on recent and ongoing work by the speaker and his colleagues, the talk presents key functionality, concepts, and techniques relating to spatial web querying; it presents functionality that addresses different kinds of local intent; and it outlines directions for the future development of keyword-based spatial web querying.

Using Semantic Knowledge to deal with Contradictions in Robotics Alessandro Saffiotti - SFB/TR 8 Colloquium Orebro University, Sweden We the humans know the semantics of the environment where we live. We know the function of objects and places around us, we know which objects belong to which place, and so on.  We use this knowledge when we plan our activities, and when something in our plans go wrong. Robots should do the same.  However, it is only recently that researchers in autonomous robotics have started to endow robots with semantic knowledge, and with the ability to reason from this knowledge.  In this talk, I will outline the efforts in this direction performed at the AASS Cognitive Robotic Systems Lab of Orebro University, Sweden.  Our effort are based on a specific type of semantic maps, which integrates hierarchical spatial information and semantic knowledge, and leverage this knowledge to facilitate taskplanning and reasoning about exceptions.  I will focus in particular on the second issue: how can semantic knowledge allow a robot to recognize when things are NOT as they should be, and provide indications to correct these deviations.  I will discuss in particular the generation of goals from semantic knowledge. For instance, if a robot has semantic knowledge that perishable items must be kept in a refrigerator, and it observes a bottle of milk on a table, this robot will generate the goal to bring that bottle into a refrigerator.This work was done in cooperation with Cipriano Galindo, from the University of Malaga, Spain.  Date: 14.11.2014 Time: 15:30 h Location: Cartesium, Bremen Speaker-URL`s: Alessandro Saffiotti (MSc, PhD) is full professor of Computer Science at the University of Orebro, Sweden, where he heads the AASS Cognitive Robotic Systems laboratory.  He holds a MSc in Computer Science from the University of Pisa, Italy, and a PhD in Applied Science from the Universite Libre de Bruxelles, Belgium.  His research interests encompass artificial intelligence, autonomous robotics, and technology for elderly people.  He is the inventor of the notion of "Ecology ofphysically embedded intelligent systems", a new approach to include robotic technologies in everyday life that has been applied in several projects.  He is the initiator of a series of ongoing international initiatives on combining AI and Robotics.  He has published more than 160 papers in international journals and conferences, and organized many international events.  He is or has been P.I. in a dozen EU projects and networks.  He is a member of AAAI, a senior member of IEEE, and an ECCAI fellow.]]> news Kolloquien calendar Fri, 14 Nov 2014 11:00:00 +0100 Symposium Spatial Language Modules This symposiums aims to shed light on and discuss the nature of the components that subserve spatial information processing and communication, that is, spatial language modules, from an interdisciplinary perspective.

Given a relevant text corpus, conceptual spaces can be induced from data by using dimensionality reduction methods such as multi-dimensional scaling. To date, conceptual spaces are mainly used for measuring similarity. In this talk, I will argue that many aspects of semantic relatedness can be identified with qualitative spatial relations in conceptual spaces, and that this allows us to learn symbolic knowledge about categories in a purely data-driven way. As a simple example, the spatial part-of relation corresponds to the conceptual is-a relation, which is useful for automatically refining taxonomies. Second, spatial betweenness in conceptual spaces is useful for identifying “intermediary concepts”. For example, we can think of a tapas bar as being intermediate between a pub and a restaurant, and accordingly we can expect the representation of “tapas bar” to be geometrically between the representations of “restaurant” and “pub” in a conceptual space of places. Finally, relative attributes such as “more violent than” (for films) or “more tannic than” (for wines) can be associated with direction relations in a conceptual space. The aforementioned spatial relations are useful for implementing various patterns of commonsense reasoning. Betweenness, for example, can be used to implement a symbolic counterpart to numerical interpolation, e.g. from the knowledge that bars and restaurants sell drinks, we derive that tapas-bars are also likely to sell drinks. Direction relations are useful for implementing a fortiori inference (and other forms of analogical reasoning). For example, given that Die Hard has received an 18 certificate from the British Board of Film Classification and that Drive is more violent than Die Hard, we can plausibly derive that Drive has also received an 18 certificate. I will report the result of experiments that show the usefulness of the aforementioned patterns of commonsense reasoning. For example, we have found that a betweenness based classifier, using a conceptual space of place types induced from Flickr, outperforms humans in categorising places from the Foursquare and Geonames taxonomies. Similarly, by identifying qualitative direction relations in a conceptual space of films (derived from a large corpus of film reviews), we can implement a form of analogical reasoning which outperforms standard classifiers such as SVMs, kNN and C4.5 in a variety of film related categorisation tasks. Bio: Steven Schockaert studied computer science at Ghent University, where he also defended his PhD thesis in 2008 on "Reasoning about fuzzy temporal and spatial information from the web". This thesis was awarded with the 2008 ECCAI Artificial Intelligence Dissertation Award and the IBM Belgium Prize for Computer Science. After his PhD, he obtained a postdoctoral fellowship from the Research Foundation - Flanders. In September 2011 he became a lecturer at Cardiff University, where he currently works. His current research interests are largely centred around three areas: multi-valued logics, commonsense reasoning, and geographic information retrieval. In the area of multi-valued logics, he is mainly working on Łukasiewicz logic (e.g. automated reasoning and complexity) and on extensions of answer set programming, a form of logic programming based on the notion of stable models. In the area of commonsense reasoning, he looks at qualitative techniques for managing imperfect knowledge bases, including possibilistic logic and qualitative approaches to similarity-based and analogical reasoning. Finally, in the area of geographic information retrieval, his main focus is on acquiring geographic information from semi-structured web resources Date: 27.06.2014 Time: 15:30 h Location: Cartesium, Bremen Speaker-URL: ]]> Kolloquien news calendar Fri, 27 Jun 2014 00:00:00 +0200 SPATIAL REASONING WITH MIRRORS Achille Varzi - SFB/TR 8 Colloquium, Special Date!

How can we use an understanding of place to facilitate how people engage with each other, and improve lives? Such are the questions that drive Information Grounds—a place-based framework pioneered by Canadian information scientist Dr. Karen E. Fisher with colleagues at the University of Washington, Michigan, and Microsoft using varied methods over 20 years’ of study. Information Grounds is a lens for understanding information flow in informal social settings—informal, temporal social settings where people gather for a focal, instrumental purpose, and create, remix, and share information using degree technology of any degree.  Information Grounds can occur anywhere—football match, hair salon, rock convert, at the beach, tailgate party, dog park. or pub; sometimes though people may not be there by personal choice as in the case of queues or waiting offices, classroom hallways; and disaster, crisis and refuge contexts. Most simply, Information Grounds are predicated on the presence of people (usually 2 or more) in any physical or online setting; however the quality of Information Grounds will range from abysmal to superb, depending on how well their collective attributes facilitate the creation and sharing of information among individuals. Information Grounds comprise a people-place-information trichotomy with 15 facets; it premises that by understanding the characteristics of the people present (e.g., demographics, motivation, number, connectedness, and social type), the characteristics of the place itself (e.g., victuals, safety, location, comfort) and the characteristics of the information experience (in broadest post-modernist sense), design options can be created to support that information ground for varied topics.  At the University of Washington, Information Grounds is taught to all iSchool students from undergraduate to PhD; within information science, Information Grounds is widely respected as a robust approach to understanding and designing around people, place and information, be it for specific populations (e.g., aged, teens, people dealing with illness) or physical context (hair salon, library, shopping malls), or type of information (health, civic). Dr. Fisher will overview research on peoples’ everyday Information Grounds as well as those that arise during crisis and disaster, and discuss the implications for designing applications and policy. Her early research with immigrants/refugees in New York, work for the Gates Foundation/IMLS post-Katrina on the impact of computers in U.S. public libraries, and current mixed-methods design work with immigrant and refugee youth from Eastern Africa and South-East Asia suggest that Information Grounds are a universal phenomenon, and that interventions based around people-place-information factors hold great potential for strengthening social fabric.
