======================================================================= MECAHNISMS OF MEANING 2010: HW2 Raquel Fernandez, ILLC ======================================================================= Semantic Annotation Exercise Task: Decide, for each sentence in a data set from SemEval-1, whether two nouns bear the semantic relation Content-Container. 1. Download the data set and the definition of the semantic relation from the course website. 2. Read the definition of the semantic relation carefully; it includes examples of positive and negative instances. 3. Annotate the data set according to your understanding of the definition, indicating whether the relation holds (true) or not (false). - create a text file or a spreadsheet file (using excel or open office) - use one line (or raw) per item in the data set (there are 70 items; your annotation file should have 1 column and 70 raws) - write `true' if the relation holds and `false' if it doesn't. your annotation file should look like this: true false true true ... with raw 1 corresponding to item 001, raw two to item 002, ... etc. (do not write the item number on the annotation file, only `true' or `false'). - Do the annotation independently without discussing among yourselves! There are no `correct' nor `incorrect' annotations. Your own judgement is all that counts. => The annotation file is due on Monday 4 October. Send it to me via email as an attachment (text, excel or open office format). with your name (e.g. yourname-annotation.txt). 4. On a different file or on a piece of paper, make a note of those examples where you were doubtful between `true' and `false'. What was the problem? In those cases where you chose `false', which semantic relation would have been appropriate? Here are a few possibilities (feel free to come up with more): - Cause-Effect (e.g., virus-flu) - Instrument-Agency (e.g., laser-printer) - Product-Producer (e.g., honey-bee) - Origin-Entity (e.g., rye-whiskey) - Theme-Tool (e.g., soup-pot) - Part-Whole (e.g., wheel-car) This does not have to be submitted; we'll dicuss it in class.
