Quote from Wikipedia, the free encyclopedia
Text mining, sometimes alternately referred to as text
data mining, roughly equivalent to
text analytics, refers generally to the process of deriving high-quality
information from text. High-quality information is typically derived through the dividing of patterns and trends through means such as
statistical pattern learning. Text mining usually involves the process of structuring the input text (usually parsing, along with the addition of some derived linguistic features and the removal of others, and subsequent insertion into a
database), deriving patterns within the structured data, and finally evaluation and interpretation of the output. 'High quality' in text mining usually refers to some combination of
relevance,
novelty, and interestingness. Typical text mining tasks include
text categorization,
text clustering,
concept/entity extraction, production of granular taxonomies,
sentiment analysis,
document summarization, and entity relation modeling (i.e., learning relations between
named entities).
HistoryLabour-intensive manual text-mining approaches first surfaced in the mid-1980s, but technological advances have enabled the field to advance swiftly during the past decade. Text mining is an
interdisciplinary field which draws on
information retrieval,
data mining,
machine learning,
statistics, and
computational linguistics. As most information (over 80%[
citation needed]) is currently stored as text, text mining is believed to have a high commercial potential value. Increasing interest is being paid to multilingual data mining: the ability to gain information across languages and cluster similar items from different linguistic sources according to their meaning.
Alpha 出遊團繼上次到台東知本後，本次的行程是宜蘭的太平山，一直以來很想去玩的地方。（以前去是大學山地服務出團，心情很不同。）
傳統藝術中心裡有個"粉墨登場"的舞台很妙，在不顯眼處位於其的左上方畫有我們想都想不到的圖樣，大同寶寶、乖乖、王子麵，以及蝦味先等等，原本還以為是導遊在開我們玩笑呢。 
一早即出發到歐式水上市場，這也是我最期待的景點之一，果然沒讓我失望，在輕舟上購物是個新鮮的體驗，小販們販售的水果也都好新鮮好甜又juicy！我們喝了大象蛋-椰子水，吃了蓮霧、香蕉、荔枝和白柚等等。二姐夫點了碗米粉湯，品嚐後直說yammy~yammy~後來導遊告訴我們小販的水都是在船上直接舀取河水烹煮......，難怪特別好吃喔！（還好我沒搶來吃...嘻嘻）
幾個表演中最有看頭的非"大象趣味表演秀"莫屬了。我們一看到大象就開始興奮high得不得了，猛想要和大象合照，也不顧小費一人要50泰株的拼命給拼命拍，結果後來的行程包含大自然之旅和Dream World都有大象，就覺得自己當時真好笑。
