  • We present a method to discover robust and interpretable sociolinguistic associations from raw geotagged text data. Using aggregate demographic statistics about the authors’ geographic communities, we solve a multi-output regression problem between demographics and lexical frequencies.

  • A standard form of analysis for linguistic typology is the universal implication. These implications state facts about the range of extant languages, such as “if objects come after verbs, then adjectives come after nouns.” Such implications are typically discovered by painstaking hand analysis over a small sample of languages. We propose a computational model for assisting at this process. Our model is able to discover both well-known implications as well as some novel implications that deserve further study.

  • Speech recognition problems are a reality in current spoken dialogue systems. In order to better understand these phenomena, we study dependencies between speech recognition problems and several higher level dialogue factors that define our notion of student state: frustration/anger, certainty and correctness. We apply Chi Square (χ2) analysis to a corpus of speech-based computer tutoring dialogues to discover these dependencies both within and across turns.

  • Semantic relatedness is a very important factor for the coreference resolution task. To obtain this semantic information, corpusbased approaches commonly leverage patterns that can express a specific semantic relation. The patterns, however, are designed manually and thus are not necessarily the most effective ones in terms of accuracy and breadth. To deal with this problem, in this paper we propose an approach that can automatically find the effective patterns for coreference resolution.

  • We expect the overall trend of declining household size to persist. This is supported by an analysis of a panel of 38 countries over time: by the year 2027 on average 3.8 people will live in a Turkish household – still significantly more than in west European house- holds today. Furthermore, we have assumed a slowdown in migration as push and pull factors for moving are weakening.

  • Sustainable development has been one of the alarming concerns in the twenty-first century. Anderson and Brooks (1996) discus how given the fact that “the supply of most natural resources and environment services” are limited, it is of urgent concern to monitor and control resource usage for one to even hope for continued economic activity in the years to come. Furthermore, the incessant population and per capita growth exacerbates the problem as they are indicative of the continuous growth in economic activity (Anderson & Brooks, 1996).

  • Similarly, looking at the database of human health, total outpatient (OPD) visits, and the percentage shared by the respiratory disease (ARI) for two years, it quite clearly reflects the increasing trend of respiratory disease. From 1996 till 1998, number of ARI patient is increasing at the rate of 22.89 percent per year. Similarly, share of ARI patient out of total OPD visit has been increased from 9.99 to 10.11 percent within the same span of time.

  • In [2], the problem of discovering sequential patterns over large databases of customer transactions is considered. The proposed algorithms generate a data sequence for each customer from the database and search on this set of se- quences for a frequent sequential pattern. For example, the algorithms can discover that customers typically rent “Star Wars,” then “Empire Strikes Back,” and then “Return of the Jedi.

  • The study of graphic design history, in terms of its influential position in western societies, is crucial to the relevance of contemporary graphic design – to provide a comprehension of why things are the way they are, and how they came to be that way. Cultural progressions, political events, societal developments, and technological advancements shape and drive our way of life. Throughout history, graphic design has played an influential role in giving a visual voice to these narratives. In short, “graphic design history is world history”2 .

  • Tracking system status is one thing. Solving discovered problems is another. Systems Director is designed to help you accomplish both. Using the Scoreboard, you can identify the number of systems with problems in your data center. The ability to drill down to view the specific problems on a system is intuitively integrated into the Health Summary view (and throughout Systems Director). This display reflects any known problems with your hardware, as well as triggered threshold monitors, in a single status overview.

  • We do the research that identifies causes of disease and disability. We advocate for solutions. We consult with policymakers and provide them with the evidence they need to make change. We roll our sleeves up and get to work in communities by influencing policies, identifying trends, implementing solutions, and increasing healthy behavior. Our work happens on a molecular level, and on a population-wide level. Microbiologists work to find a vaccine for malaria, while behavioral scientists research ways to discourage populations from smoking.

  • In some event detection applications, events of interest occur over a relatively small proportion of the total time: e.g. alarm generation in surveillance systems, and extrac- tive summarization of raw video events. The automatic de- tection of temporal events that are relevant, but whose oc- currence rate is either expected to be very low or cannot be anticipated at all, constitutes a problem which has recently attracted attention in computer vision and multimodal pro- cessing under an umbrella of names (abnormal, unusual, or rare events) [17, 19, 6].

  • Parsing systems which rely on hand-coded linguistic descriptions can only perform adequately in as far as these descriptions are correct and complete. The paper describes an error mining technique to discover problems in hand-coded linguistic descriptions for parsing such as grammars and lexicons. By analysing parse results for very large unannotated corpora, the technique discovers missing, incorrect or incomplete linguistic descriptions. The technique uses the frequency of n-grams of words for arbitrary values of n.
