We present SPOQL, a structured query language for Semistructured Probabilistic Object (SPO) model . The original querylanguage—SP-Algebra , has traditional limitations like terse functional notation and unfamiliarity to application programmers. SPOQL alleviates these problems by providing familiar SQL-like declarative syntax. We show that parsing SPOQL queries is a more involving task than parsing SQL queries. We also present an eagerevaluation algorithm for SPOQL queries
