Problem Description Sleep-disordered breathing (SDB) is a common and highly prevalent condition in children, affecting up to 27 percent of children, with a median in the 10 percent to 12 percent range. Rather than being an "all of nothing" condition, SDB is traditionally perceived as encompassing a wide spectrum of clinical severity - ranging from habitual snoring to obstructive sleep apnea syndrome (OSAS). A research team is interested in identifying relevant patterns associated with existing research trends[1] - the objective is to index and analyze documents associated with research in this area with the intent of identifying logical patterns in the text. To get you started, the team has provide 247 article abstracts associated with the treatment and outcomes of SDB. The abstracts were scraped from PubMed. The team is interested in identifying what research is being discussed in the 247 article abstracts and how it might be related to the larger body of research surrounding SDB. Keep in mind that some research might be expected, while others might not. Unexpected findings may help research team form new hypotheses to test. [1] Carole L.
