Assignment 6: Metadata
Readings: Holland et al., WordNet chapters, Bates '88, Svenonius, Pitts-Moultis and Kirk, OI chapters 1-8.
The goal of this assignment is to give you hands-on experience with three aspects of metadata:
(1) XML Data DTD Construction and Dublin Core Description
The assignment has three parts:
The items that you are to describe are:
To create the metadata description simply use a word processor and mark up your description of these items using the DTD created in part 1. Your description should go into the appropriate elements defined by your DTD -- the content should be based on what you find at the OCLC site You shouldn't need to read all of the information on the web sites to be able to do these descriptions, just enough so that you have a good idea of what they are about and how to describe them.
Be sure to include your DTD along with your marked-up descriptions.
Assume also that following types of metadata have been assigned to each recipe:
Also, some of the categories in the Main Ingredient facet have hierarchical structure. For example, under Seafood are the subcategories Fish and Shellfish, and under Poultry are the subcategories Chicken, Turkey, and Duck. (Feel free to add more hierarchical structure to other categories as necessary.)
(A) Create a faceted classification system that can be used to describe these dishes. Show how each dish can be classified within the classification system. Your design must take into account the fact that at least one facet is hierarchical (Main Ingredient). You don't have to show the entire classification system; only those parts that are needed to classify the dishes shown. Briefly explain/justify your classification system.
(B) Create a hierarchical classification system that can be used to describe these dishes, and show how the dishes can be classified within the system, using all of the types of metadata shown. Your design must take into account the fact that at least one facet is hierarchical (Main Ingredient). You don't have to show the entire hierarchy; only those parts that are needed to classify the dishes shown. Briefly explain/justify your classification system.
(3) Lexical Relations and Conceptual Relations using WordNet
(A) Select a noun that has at least two synsets assigned to it. Draw a sketch of links to/from this synset to other synsets. For at least two senses of the selected word, show at least one hypernym, one hyponym, and one other type of lexical relation.
(B) Name a conceptual relation that can associate a concept with the word you chose but which is not a valid WordNet lexical relation. For example, for the word tennis, a conceptual relation that might hold between it and racquet is instrument. (Do not use instrument as your example!)
