We report grammar inference experiments on partially parsed sentences taken from the Wall Street Journal corpus using the inside-outside algorithm for stochastic context-free grammars. The initial grammar for the inference process makes no ,assumption of the kinds of structures and their distributions. The inferred grammar is evaluated by its predicting power and by comparing the bracketing of held out sentences imposed by the inferred grammar with the partial bracketings of these sentences given in the corpus.

We present a stochastic parsing system consisting of a Lexical-Functional Grammar (LFG), a constraint-based parser and a stochastic disambiguation model. We report on the results of applying this system to parsing the UPenn Wall Street Journal (WSJ) treebank. The model combines full and partial parsing techniques to reach full grammar coverage on unseen data. The treebank annotations are used to provide partially labeled data for discriminative statistical estimation using exponential models.

the award allowing me to teach in Germany for a year; the
University of Erfurt, which gave me a home where I could
do that teaching; and Rowan University, which has provided
generous institutional support during the writing of this
Even though I was now walking with Jesus, I still hated myself. Any self-worth that I ever had was in what I looked like, and I had gained weight. The beauty of youth started to fade as it always does. I was completely worthless in my own eyes. I hated myself. The reason I hated myself was because I was fat.
The assignment sounded forbidding. The ﬁnal project for the colloquial sem
inar in philosophy appeared in my hands three weeks before the end of the
spring semester, 1973. Though it was straightforward enough, selecting the
dozen most inﬂuential individuals in history and defending the choices was
a task this college sophomore found at once both onerous and intriguing. The
professor did not really expect college students to come up with twelve names
and defend them, did he? He did.
The explosion brought Jim Peters upright in bed. He sat there, leaning back on the heels of his hands, blinking stupidly at the wall. His vision cleared and he looked down at Myra, just stirring beside him. Myra opened her eyes. Jim said, "Did you feel that?" Myra yawned. "I thought I was dreaming. It was an explosion or something, wasn't it?" Jim's lips set grimly. After ten
In these days immediately following the Great War it is well upon beginning anything--even a modest
biographical sketch--to consider a few elementals and distinguish them from the changing unessentials, to
keep a sound basis of sense and not be led into hysteria, to look carefully again at the beams of our house and
not be deceived into thinking that the plaster and the wall paper are the supports of the building.
Let us consider a few of these elementals that apply to the subject in hand as well as to the rest of the
universe--elemental truths which do not change, which no Great War can...
We investigate the eﬀect of corpus size in combining supervised and unsupervised learning for two types of attachment decisions: relative clause attachment and prepositional phrase attachment. The supervised component is Collins’ parser, trained on the Wall Street Journal. The unsupervised component gathers lexical statistics from an unannotated corpus of newswire text. We ﬁnd that the combined system only improves the performance of the parser for small training sets.

Coxe describes the spectacular rise and fall of technology and telecom stocks as a "Triple Waterfall," a technical analyst's term for a classic boom-and-bust event. In events like these, vast amounts of wealth change hands from investors to those who profit from the bubble, in this case the upper management of dot-coms and the like who cashed in big at the top by selling stock and exercising stock options. According to Coxe, "Triple Waterfalls aren't mere bubbles, they are financial pandemics that take not months, not years, but decades to run their course.

“Not more than half a dozen really good books about investing have been written in the past fifty years. This one may well be the classics category.” ----- FORBES This is a detailed abstract of the book. The opinions in the abstract only reflect those of the author’s not mine, though I largely agree with most of his opinions. The “I” in the abstract refers to the author. If you are only interested in how to make investment, you can read Part four directly. However, I strongly suggest you read the whole abstract....

In November of 2000, The Wall Street Journal asked me to write
an opinion piece on Jack Welch’s choice of a successor. The essay,
entitled Welch’s Successor is likely to Succeed, included the following
proclamation: “Welch has done more to advance the body of
knowledge than any of his contemporaries. He created a new business
lexicon.” This statement planted the seed for this book...that
the very words, terms, and phrases used most often by Jack
Welch, 250 in all, could become the basis for a management book....
