Adding structure to unstructured data
- In 6th Int. Conf. on Database Theory (ICDT ’97),LNCS 1186, 336–350
, 1997
"... We develop a new schema for unstructured data. Traditional schemas resemble the type systems of programming languages. For unstructured data, however, the underlying type may be much less constrained and hence an alternative way of expressing constraints on the data is needed. Here, we propose that ..."

A Query Language and Optimization Techniques for Unstructured Data
, 1996
"... A new kind of data model has recently emerged in which the database is not constrained by a conventional schema. Systems like ACeDB, which has become very popular with biologists, and the recent Tsimmis proposal for data integration organize data in tree-like structures whose components can be used ..."

Anonymity in Unstructured Data
"... In this paper we study the problem of protecting privacy in the publication of set-valued data. Con-sider a collection of transactional data that contains detailed information about items bought together by individuals. Even after removing all personal characteristics of the buyer, which can serve a ..."

Anonymizing Unstructured Data
, 2008
"... In this paper we consider the problem of anonymizing datasets in which each individual is associated with a set of items that constitute private information about the individual. Illustrative datasets include market-basket datasets and search engine query logs. We formalize the notion of k-anonymity ..."

-anonymity for set-valued data as a variant of the k-anonymity model for traditional relational datasets. We define an optimization problem that arises from this definition of anonymity and provide O(k log k) and O(1)-approximation algorithms for the same. We demonstrate applicability of our algorithms
Approaches for Managing and Analyzing Unstructured Data
"... Abstract — Large volumes of data that will be stored and accessed in future is unstructured. The unstructured data is generated in a very fast pace and uses large storage areas. This increases the storage budget. Extracting value from this unstructured data which balances the budget is the most chal ..."

Answering structured queries on unstructured data
- In WebDB
, 2006
"... There is growing number of applications that require access to both structured and unstructured data. Such collections of data have been referred to as dataspaces, and Dataspace Support Platforms (DSSPs) were proposed to offer several services over dataspaces, including search and query, source disc ..."
