Example Markovian streams include text inferred from speech, location streams inferred from GPS or RFID readings, and human activity streams inferred from sensor data. Lahar supports OLAP-style queries on Markovian stream archives by leveraging novel approximation and indexing techniques that efficiently manipulate stream probabilities.\n          <\/jats:p>\n          <jats:p>This demonstration allows users to interactively query a warehouse of imprecise text streams inferred automatically from audio podcasts. Through this interaction, the demo introduces users to the challenges of Markovian stream processing as well as technical contributions developed to address these challenges.<\/jats:p>","DOI":"10.14778\/1687553.1687605","type":"journal-article","created":{"date-parts":[[2014,6,24]],"date-time":"2014-06-24T12:17:57Z","timestamp":1403612277000},"page":"1610-1613","source":"Crossref","is-referenced-by-count":2,"title":["Lahar demonstration"],"prefix":"10.14778","volume":"2","author":[{"given":"Julie","family":"Letchner","sequence":"first","affiliation":[{"name":"University of Washington"}]},{"given":"Christopher","family":"R\u00e9","sequence":"additional","affiliation":[{"name":"University of Washington"}]},{"given":"Magdalena","family":"Balazinska","sequence":"additional","affiliation":[{"name":"University of Washington"}]},{"given":"Matthai","family":"Philipose","sequence":"additional","affiliation":[{"name":"Intel Research Seattle"}]}],"member":"320","published-online":{"date-parts":[[2009,8]]},"reference":[{"key":"e_1_2_1_1_1","volume-title":"A forecast of worldwide information growth through","author":"DC.","year":"2010","unstructured":"I DC.
