In this paper, we describe the lessons we learned in developing AgentBuilder, a commercial system for rapidly creating agents that extract information from web sites. AgentBuilder employs a Programming-by-Example (PBE) paradigm, where users train the system by showing the system examples of web pages and the information to be extracted from these pages. The system uses a sophisticated machine l...

In open settings, the participants are autonomous and there is no central authority to ensure the felicity of their interactions. When agents interact in such settings, each relies upon being able to model the trustworthiness of the agents with whom it interacts. Fundamentally, such models must consider the past behavior of the other parties in order to predict their future behavior. Further, i...

The goal of this paper is to offer a detailed description of sentences like (1), which I will label ‘minimal ne. . . que realizations’. It is a description in the sense that I make explicit the makeup of this structure: it contains hidden material, and I show what this material is (Section 2). It is also a description of the many theoretical problems posed by ne. . . que: the core problem arise...

I examine a model where agents differ in their discount factors. It has long been known that in the long-run, the most patient household or individual ends up owning all the capital, provided there is a maximum sustainable stock. I show that this is no longer true when there is sustained growth. I examine a model where there is endogenous growth due to learning-by-doing, the “Arrow-Romer” model...

A longstanding puzzle in the semantics/pragmatics of questions has been the subtle differences between positive (e.g. Is it . . . ? ), low negative (Is it not . . . ? ), and high negative polar questions (Isn’t it . . . ? ). While they are intuitively ways of asking “the same question”, each has distinct felicity conditions and gives rise to different inferences about the speaker’s attitude tow...

archetypes did have empirical virtues. And, of course, Owen achieved remarkable scientific successes, as with his work on the New Zealand moas, the Madagascar aye-aye, and the great apes. Was it a defect in Huxley's opportunistic character that caused him to turn against Owen, initially his patron? By Rupke's account, it may seem that, from a psychological perspective, it was Huxley who was the...

The dynamic properties of the optimal growth model are examined, based on a one good and two factor-labor and capital--model with a labor-surplus economy due to a fixed wage rate. If the average capital productivity is higher than the time discount rate which is assumed to be larger than the population growth rate, then the economy reaches the full employment stationary state in a finite amount...

A sense-based lexical knowledgebase is a core foundation for language engineering. Two important criteria must be satisfied when constructing a knowledgebase: linguistic felicity and data cohesion. In this paper, we discuss how data cohesion of the sense information collected using the Sinica Sense Management System (SSMS) can be achieved. SSMS manages both lexical entries and word senses, and ...

Adjectives are typically felicitous in within-predicate comparisons—constructions of the form ‘X is more A than y’, as in This is bigger than that, but are often infelicitous in between-predicate comparisons—constructions of the form ‘X is more A than (y is) B’, as in *Tweety is bigger than (it is) heavy. Nouns, by contrast, exhibit the inverse pattern. The challenge is to ac...
